Using the Kiosk User Interface
The following sections give an overview of the end user experience in using the MetaDefender Kiosk.
The exact experience will depend on how each MetaDefender Kiosk instance is configured.
Launching MetaDefender Kiosk
Before v4.6.2, MetaDefender Kiosk accepted all of sensitive keystrokes including the combinations that could be abused to gain system control, even by using HID attack platforms. From 4.6.2 moving forwards, those sensitive and vulnerable-to-abuse keystrokes are disabled, and only re-anabled when KIOSK UI application is not running. Generally, only keystrokes really applicable on KIOSK input areas are allowed.
The MetaDefender Kiosk application automatically launches upon system startup. If there is a system malfunction and you restart the system, MetaDefender Kiosk re-initializes upon startup.
After startup, the idle screen is displayed:
If the MetaDefender Kiosk license is expired or invalid, the MetaDefender Kiosk application displays an error and does not allow usage:
Exiting the User Interface
Alt+S is used to exit the UI.
When exiting the UI, it may take a few minutes if Kiosk is in the middle of processing media. It is not recommended to exit the UI while Kiosk is processing media.
It is strongly suggested to set Exit Credentials (either a password or AD administrator credentials) in order to prevent users from accessing the underlying system. If the Kiosk software is experiencing any malfunction, the UI will not be able to exit and close. The system administrator will have to have to reboot the machine and diagnose the services' operation in Safe Mode.
